Supaslate has been designed to be the perfect lightweight plastic alternative to natural roofing slate. Our synthetic slate is manufactured to a high standard in Great Britain, as a unique triple slate design which is easy snapped to single slate for a fast and easy installation to most roofing applications.
Fast Installation

Our Tiles use a 'Snap to Single' system making installation faster, they come in a bank of 3 tiles and can be laid 3 tiles at once or just snap one or two tiles off depending on how many you need. this results in a much faster installation and minimizes waste.
